Substituted methyl isopropyl oxocyclohexane derivatives, organoleptic uses thereof and process for preparing same

Abstract

Described is the genus of compounds defined according to the structure: ##STR1## wherein at least one of the lines: [++++] represents a carbon-carbon single bond and the other of the lines: [++++] represents a carbon-carbon double bond or a carbon-carbon single bond; wherein the moiety X represents one of the moieties: ##STR2## wherein when the moiety X has the structure: ##STR3## then one of the lines: [++++] is a carbon-carbon double bond and the other of the lines: [++++] is a carbon-carbon single bond and when the moiety X has the structure: ##STR4## then both of the lines: [++++] represent carbon-carbon single bonds; wherein, one of R 1 , R 2 and R 3 represent 2-methyl-1-propenyl or 2-methyl-1-propylidenyl; and the other of R 1 , R 2 and R 3 represent hydrogen; with the provisos that: (i) when the line: [++++] at the 3-4 position is a double bond, then R 3 is hydrogen or 2-methyl-1-propenyl; and (ii) when the line: [++++] at the 2-3 position is a double bond, then R 2 is hydrogen or 2-methyl-1-propenyl. with the members of said genus being novel compounds useful in augmenting or enhancing the aroma or taste of consumable materials including perfume compositions, colognes and perfumed articles (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, cosmetic powder compositions, fabric softener compositions and fabric softener articles).

What is claimed is: 
     
       1. A substituted methyl isopropyl oxocyclohexane derivative defined according to the structure: ##STR149## wherein at least one of the lines [++++] is a carbon-carbon single bond and the other of the lines [++++] is a carbon-carbon single bond or a carbon-carbon double bond; wherein X represents the moiety: ##STR150## wherein when the moiety X has the structure: ##STR151## then one of the lines:   [++++]     is a carbon-carbon double bond and the other of the lines:     [++++]     is a carbon-carbon single bond and when the moiety X has the structure: ##STR152## then both of the lines:     [++++]     represent carbon-carbon single bonds; wherein one of R 1 , R 2  or R 3  is 2-methyl-1-propenyl or 2-methyl-1-propylidenyl; and the other of R 1 , R 2  or R 3  is hydrogen; with the provisos that:   (i) when the line:   [++++]        at the 3-4 position represents a carbon-carbon double bond R 3  is hydrogen or 2-methyl-1-propenyl; and   (ii) when the line;   [++++]        at the 2-3 position is a carbon-carbon double bond, R 2  is hydrogen or 2-methyl-1-propenyl.   
     
     
       2. The compound of claim 1 having the structure: ##STR153## wherein one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines is a carbon-carbon single bond and wherein one of R 1 , R 2  or R 3  is 2-methyl-1-propenyl or 2-methyl-1-propylidenyl and the other of R 1 , R 2  and R 3  is hydrogen; with the provisos that: (i) when the dashed line at the 3-4 position represents a carbon-carbon double bond R 3  is hydrogen or 2-methyl-1-propenyl; and   (ii) when the dashed line at the 2-3 position is a carbon-carbon double bond, R 2  is hydrogen or 2-methyl-1-propenyl.   
     
     
       3. The compound of claim 1 having the structure: ##STR154## wherein one of R 1 , R 2  or R 3  is 2-methyl-1-propenyl or 2-methyl-1-propylidenyl, and the other of R 1 , R 2  or R 3  is hydrogen.
